Just finished the necessary three runs through of Nier Automata to experience the full story.
Great, varied gameplay, superb story with depth and intelligence, incredible soundtrack. Managed all of the directly accessible bosses on hard, but to get to the two super-tough hidden bosses would've required a lot of tedious grinding to raise my level from 72 to 99 and to fully upgrade all the weapons. Kept my saves, maybe I'll return sometime for punishment.
Completely agree with the game's reputation - it's a masterpiece.
